This looks to me like a bug (or at least an oversight) in the dependency
plugin. I presume this is what you are using to copy all the jars into a
directory before building your "installer"?
Duplicate artifactIds are not normally a problem for maven; the classpath it
builds for compiling, testing, etc will look like
-classpath
$M2REPO/group1/artifact1/artifact1-1.0.jar;
$M2REPO/group2/artifact1/artifact1-1.0.jar
which is absolutely no problem.
The problem only comes when something like the dependency plugin tries to copy
all the files into a single flat directory.
I think that the dependency plugin should check for duplicate artifactId values
in the set of files it is extracting, and if one is found then use a "full"
jarname, eg
groupid-artifactid-version.jar
for the file it writes, instead of the "short" name.
However that's no use to you as a workaround :-(
